Magento2 | Docker Image to Magento 2 local development | Continuous Deployment library

I have created a custom page with free text ordering functionality and called custom add to cart API to add items to the cart.

Once the item is added I need to update the cart item count with updated quantity. I tried to use

I have a list of filtered files found by grep by a specific regex, but want to use the results of that filtered list of files to further grep those results only.

Filtering a Magento 2 code base for file names only: grep -Ril (-i only because I tried to use extra filtering on regex)

getting error CRITICAL: TypeError: Argument 2 passed to Magento\Framework\View\Element\UiComponentFactory::argumentsResolver() must be of the type array, null given, called in C:\xampp\htdocs\magento2\vendor\magento\framework\View\Element\UiComponentFactory.php on linecreating a grid in admin panel

What I want to accomplish is for the form to change as the user changes the form type from the radio.

Standard basically has 2 selects (one classic and a fancier one, made with ng-select) and custom has a simple classic text input.

I am trying to change the form's functionality dynamically as the form type changes using the radio.

Besides trying to use formBuilder.group, I also tried using .setValidators on the individual inputs, but the result is the same: when I change the radio and the custom_channel_name input is shown i get this console error "Error: Cannot find control with name: 'custom_channel_name'"

What am I doing wrong and how do I properly handle reactive forms in this fashion?

What I have so far looks like this: https://i.imgur.com/n24mKs7.png , https://i.imgur.com/FfCgXFX.png

I'm trying to install Magento 2 on my local server, but when I run the command in Composer ( composer create-project --repository-url=https://repo.magento.com/magento/project-community-edition) it stops at this message and too show an error.

I have a task to locate why products are not shown to a non-logged customer after admin makes it. The fix is that if you re-index and clean cache the customer will see the new product or the second solution is to go to shared products, enter product categories and just save. Now the problem is I want to put a break point on that "save" button so I can see what goes on after that but I don't know how to find it in my project. Is there a simple way to know what code is your magento2 using on that given page/button or whatever.

I have a server running Ubuntu 20.04, nginx and varnish with letsencrypt SSL.

I have installed PHPMyAdmin to the default server block and have another server block for my actual website running magento 2.4.3. This was all working fine until i installed varnish and now when trying to load either site i get the 503 Backend fetch failed error and when i try and load then on port 8080 from the URL i get a "this page cannot be reach" error.

I have configured nginx to listen on port 8080 for both sites, i have set varnish to listen on port 80. I have edited the vcl generated by magento to set the host and port to 127.0.0.1 and 8080 respectively as shown on https://devdocs.magento.com/guides/v2.4/config-guide/varnish/config-varnish-configure.html.

The varnishlog show the backend is unhealthy error but i dont know how to solve this.
The output of netstat -tulpn is:

How can we add an external image for magento2 product detail page(not from the magento2 backend). I tried some stuff in the galley.phtml but not succeed. Is there anybody who can fix this, help me please.

Im new to both PHP and Magento2 (I come from C++). I am simply trying to add a variable from a different file to the registration.php

But I can not seem to grab the other file. The other file is located in app/code///myCode/myFile.php.

And the registration is in app/code///registration.php.

So how would I acces this other file from within the registration.php?
